Preparing the optical fibre cable for wiring
Trimming the optical fibre cable
Optical fibre cables can be trimmed without the need for special tools.
1. Place optical fibre cable on a hard surface and cut to required length using a knife, for
example.
2. In case of optical fibre cables with a PUR sheath (red), strip about 20 mm (PE material
does not need to be stripped).
)
Note!
If the ends of the optical fibre cable are not polished, the maximum cable
length is reduced by 20% (typically). Therefore, please polish the ends of the
optical fibre cable (grain: P1000) .
Installing the optical fibre cable
1. Undo the optical fibre cable compression fitting.
2. Insert end of optical fibre cable into optical fibre connector as far as it will go.
3. Tighten the optical fibre cable compression fitting.
Setting up the optical fibre cable ring
)
Note!
Do not use bending radii less than 30 mm, otherwise the maximum optical
fibre cable length is reduced by 50% for each bend (typically).
1. Connect white optical fibre connector (transmitter, TxD) of host to black optical fibre
connector (receiver, RxD) of next drive controller.
2. Connect white optical fibre connector of drive controller to black optical fibre
connector of next drive controller.
3. Connect white optical fibre connector of final drive controller to black optical fibre
connector of host.
4. Select high output power if the optical fibre cable between two drive controllers is
longer than 40 m. This is done by moving switch S1 to ON. The maximum cable
length is thus increased to 66 m (with a cable attenuation of 150 dB/km).
